8 Claims.

This invention relates to shoe fasteners, and

particularly, to an improved reversible 0r double-acting automatic lock slider therefor. In the patent to S. H. Norton et al., N0. 1,966,- 457, dated July 17, 1934, there is disclosed an automatiolock slider including a cap member having a locking prong integrally arranged therewith, with the cap member pivotally attached to a lug arranged n one wing of the slider body and having a spring for normally retaining the locking prong in looking position in the channel of the slider. There is attached to the cap member a pull for manipulating the slider from that side of the same. While such automatic lock sliders of the type as disclosed in this patent, have proven satisfactory in service, they are limited in their application, due to the fact that the pull or slider actuating means is accessible from one side of the slider only.

While various types of reversible or double-acting automatic lock sliders, i. e., a slider having cases, while such sliders would operate satisfactorily from one side of the slider, the locking means would stick or bind and not operate properly when manipulated by means from the opposite side thereof.

According to the present invention, there is provided a reversible or double-acting automatic lock slider which is strong, rugged and compact in its construction, with the parts thereof being so constructed and arranged that they can be conveniently fabricated and assembled.

' It is one of the objects of the present invention to provide an improved lock slider for slide fasteners which can .be easily manipulated and unlocked manually from either side thereof so as to provide a reversible or double-acting lock slider.

It is anothe robject .of the invention to provide an improved automatic lock slider of the reversible or double-acting type which consists of a minimum number of relatively inexpensive parts which can be easily and quickly assembled.

It is a further object of this invention to provide an improved reversible or double-acting lock slider which is more positive in its action than other such sliders heretofore suggested and used,

. 2. whereby the locking means can be effectively unlocked from either side of the slider and, at the same-time, will be effectively locked automatically at any point along the fastener.

- Various other objects and advantages of this invention will be more apparent in the course of the following specification and will be particularly pointed out in the appended claims.

In the accompanying drawing, there is shown for the purpose of illustration, one embodiment which my invention may assume in practice.

In the drawing:

Fig. 1 is a plan view of a slide fastener having the improved slider of my invention incorporated therewith;

Fig. 2 is a side elevational view of my improved slider;

Fig. 3 is a longitudinal sectional view thereof; and

Fig. 4 is a sectional view taken on line 44 of Fig. 1 not showing the pull members.

Referring more particularly to the drawing, there is shown in Fig. 1 a conventional type slide fastener comprising tapes or stringer-s *2, having a series of spaced-apart interlocking fastener elements 3 arranged along the opposed beaded edges thereof. There is arranged on the fastener elements for longitudinal movement therealong, a slider, generally designated at 4, comprising a hollow one-piece channelled body member having spaced upper and lower wing portions 5 and 6, respectively, which are connected at one end thereof by means of a neck portion '1. There are carried by the wing portions 5 and 6 at either side thereof, inwardly extending flange portions 8 for guiding the fastener elements through the Y-shaped channel of the slider body. The slider is adapted to be moved along the fastener elements in either direction to open or close the'fastener, in a manner well-known to in the art.

According to the present invention, as more clearly shown in Fig. 3 of the drawing, there is arranged on the outer surface of one of the wing those skilled portions, namely, the upper wing portion 5, in

the present instance, an elongated lug or loop 9 which is arranged integrally with the slider body centrally thereof and has a transverse aperture 10 arranged therein. There is mounted on and 'substantially'enclosing the lug 9 and pivotally attached thereto as at 12 at one end thereof, a locking capmember 53 having opposed side flange portions l4 and end flange portions [5. There is carried preferably by one of the side flange portions 14, a locking prong or pin it which exthe same is pivotally attached to the slider for.

actuating the same in a well-known manner.

Rearwardly of the pivotal connection l2 of the cap member IS with the lug 9, there is positioned a resilient member, preferably in the form of a compression coil spring 20,,having one end thereof resting on the outer surface of the wing cap members l3 and 23, respectively, are slightly smaller than the respective transverse apertures i and 22 in the lugs 9 and 2|, respectively, so that the pivotal bar trunnion portions of the respective pull members I9 and 30 will contact first the side flanges of the cap members and move the same about their respective pivotal connections when a pulling force is exerted on either of the pull members to move the slider along the fastener elements. It will be seen that the outer wall of the transverse openings l0 and 22 will limit the outward movement of the .respective pull members, thereby tending to portion, with the other end thereof abutting-the under side of the cap member l3 and cooperating therewith, tending to move thecap member about its-pivotal connection so as to move and maintain the locking pin or prong I 6 in the channel of the slider body. Y p

A On the outer surface of the other wing portion Bonthe opposite side of the slider body, there is mountedcentrally thereof and integrally therewith, another elongated lug or loop portion 2i similar to the lug or loop 9, having a transverse aperture 22 arranged therein directly opposite the aperture 10 in the lug 9. There is likewise mounted on this lug and substantially enclosing the same, a similar elongated cap member 23 having side flange portions 24 and end flange portions 25. The cap member 23 is pivotally attached as at 26, intermediate the length theretr; to the lug, preferably at a point directly opposite the pivotal connection l2 ofthe cap memberlSQvv ith its respective lug." It will be seen that both of the cap members l3 and 23 are substantially the same except thatthe locking cap member 13" has a locking pin or prong'lt arranged thereon. H i h There is positioned in an angularly or diagonally'ar'ranged hole or opening 21 in the neck portion. 1 .of the slider body, preferably an elongated cylindrical pin-like member 28 which extends through the lugs 9 and 21 to the underside of the cap members [3 and 23. The ends of ,the pin-like member 28 are preferably rounded, asat 29, so as to provide a better bearing surface and the pin-like member is of such length that it will just contact the underside of the cap members when they assume their normal positions, as shown in Fig. 3 of the drawing. It will be seen that one end of the pin-like member 28 contacts the locking cap member l3 On one side or forwardly of its pivotal connection at l2, and that'the other end of the pin-like member contactstheunderside. of thecap member 23 at a point'on the opposite side or rearwardly of its pivotal connection at 2'8, and preferably is lodged in the corner formedby the end flange portion .25an'd the'top wall of the cap member at the rear end thereof. It will be understoodthat the pin-like'member 28 is loosely 'positioned in the diagonal hole 21 so that it can move reciprocably therein. i

There is likewise pivotallyattached to the lug '21, a pull'member with the pivotal or-trunnion 7 portion thereof extending through the transverse aperture 22 in the lug 2| "andthrough the recesses 3| in both of the side flanges 24 of the cap 123 It be understood that both the recesses 48. and 3 :i the side flanges 4 and. o e

limit the outward movement of the cap members l3 and 23 when an excessive amount of force is exerted on. the pull members.

The improved slider of my invention functions in the following manner. When the slider is actuated by means of the pull l9 from that side of the fastener, it will be seen that the pull will move the locking cap member l3 about its pivotal connection at 12 against the action of the coil spring 20, thereby moving the locking pin or prong it carried thereby out of the slider channel and accordingly, out of engagement with the fastener elements therein. When the slider is manipulated by the pull member 3i) from the opposite side of the fastener, it will be seen that the cap member 23 is moved about its pivotal connection at 26, thereby forcing the pin-like member 23 toward the cap member I3 on the opposite side of the slider, which is moved thereby aboutits pivotal connection at l2 against'the action of the coil spring 20, so as to movethe locking pin or prong l6 out of locking engagement with the fastener elements. When the pulling force oneither of the pull members l9 and '3!) is released, it willbe seen that the locking cap member 20 is moved'automatically to locking position in the channel of the slider, due to the action of the coil spring 28. ,The action of this spring also moves the pin-like member 28, togetherwith the cap member 23, to its initial or normal position.

As a result of my invention, it will be seen that there is. provided a, reverse or double-acting automatic lock slider having a slider body which can be conveniently die-cast, thereby reducing to a minimum, the cost of such a slider. It will be seen also that the cap members l3 and 23, together with the coil spring 20 and the pinlike member 28, can be conveniently and quickly assembled on the slider body with relatively inexpensive tools and without the need necessarily of any special assembling tools or equipment.
